Update:
I've got a new Video!
(also on Youtube). As you can see, controlling
neverball this way is pretty hard :)

With the most recent Patch,
you can control the level with the balance board and the camera and menus with
the wiimote. Usage: Start neverball, connect wiimote, wait 'til the leds stop
blinking, then connect balance board. There are some timing issues right now,
so if it crashes while connecting the devices, just try again.
